7 To all whom itsmay concern:

Be it known that I, WILLIAMF. REULMANN, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Insole-Tao!-Pulling Machines, of which the following is a specification.

My invention relates to in'lprovements in tack-pulling mechanism forshocrnakersv One of its objects is to )rovide a mechanism to rapidlyextract tie tacks or nails with whic the inner-soles of shoes and bootsare secured to the last, also the tacks or nails by which the uppers areattached to the inner-sole and last.

Another object is to provide mechanism for the'above purposewhich is notliable to injure the leather in extracting the tacks. Another object isto provide simple and efficient mechanism for the above purpose, whichis not liable to injure the operator.

It further consists in certain details of form, combination andarrangement, all of which will be more fully set forth in thedescription of the accompanying drawings in which:

Figure 1 is a side elevation of a mechanism embodying my improvements,part1 broken away Fig. 2 is an enlarged contra vertical section throughthe spindle and tack extractor. Fig. 3 is an end view'ol the parts shownin Fig. 2. 4 is a perspective view of the extractor member detached.Fig. 5

Spindle B ispreferably locked against endwise move- -ment by collars b and isprovided with a pulley b.

i on the-- spindle, through which rapid motion is imduced in diameterand threaded at the end, and a shoulder 1) formed near the end. In thepreferred form the extracting member D com rises a sleeve (1 to closelyfit the reduced end ii of the spindle, and one or more claws (1 arrangedconcentrically on said sleeve.

E E represent guards havin smooth narrow rims e and concentrically boredat e to lit the end ol' the spindle. The claws of the extracting memberproject slightly beyond the edges of the guards and have V'-shaped orconverging notches d in their forward edges. The extracting member ismounted upon the spindle with a guard member upon each side, and thethree'parts clamped rigidly against the shoulder b by In operation thespindle is rapidly rotated and the last and partly finished'shoe pressedby the operator against the extractor and guards at the various pointswhere tacks or nails are to be extracted.-. The guards prevent theextractor being forced deep enough into the leather to out or injurethe" leather, and also force the leather downward away from the head ofthe tack, which is caught by the claws andwithdrawn from the last andleather and thrown outwardly away from the operator.

In the modification Fig. 5, I have shown an extracting member D ofgreater width than in Fig. 4, the claws d of which are each providedwith two V-shaped notches d d; This form of extractor is to be employedas above described, and may be preferred by some operators to the formshown in- Fig. 4.
